Water treatment turns to nature
New regulations on river pollution and biodiversity, along with a need to move towards net zero, have prompted water treatment engineers to build wetlands where plants and microorganisms filter out pollutants, leaving water clean enough to flow into rivers without doing any damage. Michael Kenward OBE looks into how they are being deployed across the UK.
